Abstract
Manufacture of the ski according to the invention takes place in the form of a preliminary stage of producing a subassembly with mechanical strength, and a single moulding stage. During the preliminary stage, a stack is formed of at least a lower reinforcement (1), a core (2) and an upper reinforcement (3), the said stack is inserted into a retractable sheath (4) and the sheath is retracted. During the single moulding stage, the lower structural elements (11, 12, 13) of the ski are placed in the mould, the subassembly with mechanical strength is placed on the lower structural elements of the ski, the mould is closed and a heat-curable polymer is injected in order to form the protective covering (15) of the ski.
